Kromer Spring Balancers (Retractors) and Zero Gravity Balancers are designed to support heavy hand-operated process tools and enables them to be operated with minimum effort. The balancers will automatically retract the tool to its initial position upon releasing it after use. An automatic arresting mechanism (ratchet lock) is available in some models. It allows setting retraction stops to keep the load suspended at predefined positions. The stops are automatically activated if the working load (tool) is moved back slowly. If pushed back fast, the mechanism remains inactive.
